Yes. it has two hulls- one on an extension, in a sense a forerunner of pontoon boats or floats used on seaplanes, or catamarans, which have two hulls.
A single hull boat has only one hull, which is the standard for boats. Catamarans have two, or twin hulls.
In order to slice through the water with ease.
This term generally refers to "catamaran-type" hulls: two separate hull bodies joined together by a strong platform or deck. Catamarans can be as small as a one-person wooden craft with two dugout hulls (Pacific Islands) to seagoing vessels of 300 feet (91 meters) in length. Catamarans are very popular as recreational and cruising boats. Most are rigged with one or more masts and larger cruising cats have masts and engines. Most of today's large Tankers have double hulls, but that refers to their inner and outer hulls which greatly increase safety and lessen the chance of oil spills that damage the environment.
A trimaran has 3 hulls, a main hull and two smaller outrigger hulls.

Traditionally built hulls were constructed of horizontal wooden planks laid in either clinker (overlapped) or carvel (butted together and smooth) formation. Nowadays, hulls are more likely to be constructed of glassfibre or metal.
well, often, boats hulls are streamlined to lower the time of a journey.
